Autonomous RC ship model
Jevická, Barbora ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This Master’s thesis deals with working on development kit, which is used for RC ship model. The basis are programmable Nucleo STM32 microcontrollers, to which other used modules are connected. The goal is to test each component and create system for navigation of the ship and wireless communication between controller and ship. GPS module and compass are used to navigate and determine the direction of the ship. Controller and ship can communicate through bidirectional wireless modules with antenna. The RC ship model can be switched between manual and autonomous modes. The main result of this thesis is autonomous movement of the ship on to a predetermined GPS coordinates and parallel communication with the user.

Device Location in Wireless Network
Szabó, Peter ; Malinka, Kamil (referee) ; Kačic, Matej (advisor)
This thesis deals with the issue of locating devices in wireless networks. It takes existing solutions as example and extends them using additional approaches. This thesis designs and describes the implementation of a prototype of a new proprietary indoor localization system used for locating devices within a WiFi network. In the final part of the thesis the testing of this system is described and its results are analysed and compared with another localization systems based on similar technologies.

Robot for Robotour 2012
Vass, Robert ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
The aim of this article is the theoretical analysis, proposal and implementation of a method for the operation of an autonomous robot for Robotour 2012 with the help of camera and sensor usage. Key issues to be faced are the computer vision, robot sensing uncertainty and the localization problem. Firstly, road extraction is achieved by using colour segmentation. Secondly, for the combination of information of different uncertain sources, Kalman Filter is proposed. Finally, the information received by the camera which serves for the building of an occupancy grid map corrected by sensors is de facto the representation of environment for the robot.

Software based optical cable documentation
Martínek, Michal ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
The focus of this work is a description of search-optic cables and cables stored in the Earth's surface suitable method and the possibility of registration of the optical paths and components in the ArcGIS geographic information system. The work set out in detail the different types of optical fibers and principles listed in the wiring examples most commonly used cables. There are additional elements used in the construction of optical networks, whether the individual connectors, hubs, etc., as well as protection features most often used for distribution of optical cables. There are also examples given options stowages routes and laying cables, and most currently with the possibility to discover a practical listing and description of these search engines non-metallic elements. The work also focuses on how these elements efficiently record to go to them quickly and easily access and simplify their close location in real space, to ensure unwanted destructive interruption, or any repair, expansion, etc.

Sensorless position control of solenoid valve
Keprt, Jaroslav ; Janák, Luděk (referee) ; Houška, Pavel (advisor)
This thesis deals with the determination of the position of the solenoid core in real time based on the measured current. The reference position of the current is used for feedback control of the solenoid. For this issue, software tool Matlab/Simulink was used. For current and temperature measurements, PCB circuits were created. The whole project was carried out on the dSPACE platform.

GPS based Localization using the Java ME application
Figurny, Radek ; Morávek, Patrik (referee) ; Růčka, Lukáš (advisor)
The task of the Master's thesis has been to develop the MIDlet, which is able to receive data from an external GPS module via Bluetooth. Data are received in the NMEA 0183 format and are processed to extract longitude, latitude, elevation, velocity, number of visible satellites and measurement accuracy of longitude, latitude and elevation. Users have a possibility to save their actual location with a short description to the cell phone’s memory. The MIDlet is also able to save a user defined way-point and navigate to this way-point. The MIDlet itself was developed in the Netbeans IDE with a software development kit (SDK) made by Nokia company. This kit is designed for the Symbian OS s60 3rd edition FP1, which contains a s60 emulator and a s60 MIDlet for a direct compilation in the cell phone. The MIDlet is made of three main parts. The first part shows a longitude, latitude, elevation, velocity, longitude and latitude measurement accuracy, date and time. The second one shows a direction of north, latitude and longitude. The last one shows a direction to the selected way-point and a distance to this location. In theoretic part of the thesis there are described the GPS navigation system, Bluetooth system, geodetic system WGS 84 and programing language Java and its part Java ME.

LPR Recognition
Trkal, Ondřej ; Richter, Miloslav (referee) ; Horák, Karel (advisor)
The thesis deals with analysis and design of system for automatic localization and recognition of the license plate. The input images are from different sources, and contain large scenic and weather variations. The aim was to create a system able to find the licence plate on the image and recognize its alphanumeric figure. In this work, there is a focus on analysis and implementation of localization and optical character recognition methods. One own and four other localization methods are compared. There are also compared three classifiers for optical character recognition. Localization and OCR methods are tested on real data and evaluated in accordance with the calculated evaluation parameters. The work also contains sensitivity analysis of the proposed system.
